Jihan Wu of Bitmain, also supposedly can still get 15% to 20% more in mining BCH than BCT with ASIC boost..asicboost does NOT work with ANY flavor of seg witness...
..thus he has slack to push this BCH protocol as a BTC replacement
Yeah...unh ... I dunno, man. Assertion does not stand the scrutiny of logic.
You know miners get to include whatever transactions are in the mempool to make their block out of, right? Like, it's entirely their choice.
So if Jihan wanted to keep on using ASICBOOST on BTC*, he'd just have to pick non-segwit transactions. His problem is solved. He doesn't need BCH to do that. And, with the BTC mempool at staggering numbers, he's got plenty to pick from.
No, 'ASICBOOST does not work on segwit' is not a probative reason for Jihan's supposed preference of BCH.
*Incidentally, I am not stipulating your assertion that ASICBOOST does not work on segwit. I am just using your hypothetical to show that your conclusion deos not follow from your postulates.
